I have got my new Pixhawk unit two weeks ago and spent a few hours on 3 separate computers in the house to try and get it to connect via USB cable. I used multiple cables, powered the Pixhawk direct from the USB port, powered it from an external lab power supply (12.0v, pulling 0.2A), I tried this on two separate Windows 10 PC’s…to no avail. I followed this procedure exactly:

However when I connected the Pixhawk via USB (after I installed the Mission Planner software as well as the USB drivers), I don’t recall the exact error but it would list it as a USB device that was unrecognised. So I tried to manually update the drivers with the PX4 Flow as shown in that tutorial, all I’d get is a USB to Serial A…B…C…D option and nothing that would be PX4 Flow. So I tried every option listed and always got a small exclamation mark in the Device Manager window and it’d never list a COM port.

After struggling with this on two PC’s, one being a laptop that I plan on using MavLink on, I thought to try it on a Windows 7 machine. Plug it in via USB with the same 12v external power supply, once connected the device shows as a COM port…and is shown as PX4 Flow. I can’t believe it. So is there an actual Windows 10 driver that works with the Pixhawk? As I’d like to have a single laptop (Windows 10) that can fully control, monitor and update my automated boat and not have to rely on a Windows 7 machine that is in my garage at home.

This link to drivers does not work says oops. I have this same problem the pixhawk and qc or MP are not talking as the pc software says you are not connected. I have also tried on two windows 10 machines and the cable is well tested and works with pi no problem. I am sure it must be a driver issue but cannot even get to the part of firmware as both apps say your not connected. Now I am as with no battery attached the pixhawk lights up from USb. But with or without external battery (I am using lipo 2 cell) same problem.

I gave up on getting it to work on Windows 10. Instead I used a linux VM and installed QGC on it. I was able to get it working in minutes and was able to focus the camera. Both the normal mode and the HD mode (to focus it) worked well. No special drivers were needed, it just worked. Now mounted and tested on my copter

I do also had oroblem with win10 as it doesn’t recognize the px4 board but on linux board it worked flowless. The wiki was written based on mission planner and with qcs parameters are not the same. So i couldn’t do the sensor calibration as it is indicated.

Recently, I started poking around with the PX4Flow as a learning experience with my hexacopter. I am not an engineer (I’m in biological sciences) but keen on learning as much as possible about coding, circuits, flying,etc. I have the PX4Flow installed and sending data, but now changed my I2C address with the jumper so as to accommodate the GPS, hence now no longer getting data. I have no idea how to set the new address in the code. Possible to provide guidance?
